Submitted by Elena Benvenuti on
 
 

It is our pleasure to announce that the X-DMS Conference will be preceded by a short course on EXTENDED DISCRETIZATION METHODS. The course will be held on Monday 7 and Tuesday 8, September 2015 just before the X-DMS2015 Conference.

How to define initial stiffness matrix for cohesive elements in ABAQUS

Submitted by pratshar on

I am trying to  model adhesive failure using cohesive elements in Abaqus. I need to define the elastic behaviour of elements using traction separation criteria.

So I wanted to know what is the E/Enn, G1/Ess and G2/Ett values for my adhesive(E=1650 MPa)?

Essential parameter/properties masonry structure modelling (ABAQUS)

Submitted by Raimy Haidar on

hai, im haidar (undergraduate-civil engineering from Malaysia)

Kindly please help me, 

currently im working on my thesis which majorly focused on the dynamic analysis of masonry (Concrete Masonry Unit) multistorey building structure,

presently, im modelling the 3 story building (including ground floor) of masonry building with block size of (200x400mm) including 10mm thickness of mortar joint

(macro-modelling) using the ABAQUS program. However, im facing few issues and confusion regarding on masonry modelling:

 

analysis Composite at Abaqus

Submitted by hamed z on

Hi every one

I try to analysis my Model at Abaqus. I want to use continume shell model to create the composite layer. The model shape is so complex and I can not use Hex meshing. Abaqus just meshing the model as Tetra element. And my problem is abaqus do not accept tetra az composite layer at element type. I try to daturm the model very smal part until may be can define hex element but its not work. There is any way I can use tetra meshing for continume shell.

Hi,

I am doing a project on the effect of forming in fatigue analysis of a component.I have .key file from dyna which I have to run analysis in abaqus. I need to carry the dyna output containing initial stress and nodal thickness into abaqus and carry analysis which I currently am not able to do it. Kindly suggest me how I can do that if u know.

How to plot multi contours in tecplot at a time from two different files.

for example i have two different excel data files A & B with node coordinate and its mises value. I  knew how to plot the individual contour in Tec plot using individual files A & B but now i want to plot both the contour on same page using these individual files (A+B). So, anyone can help me......  

What is the Mechanical properties of Spandex?

Submitted by Zezo7790 on

   Hello everyone I'm new here, Hope you can help me!

I was looking for an elastic material and I found a material called Spandex or Lycra(its trade name) I tried to find its mechanical properties on internet, but could not find specific calculation such as its Yielding stress and its modulus of elastisity(E), the most important thing i need is to find the maximum force or stress that it can stand.

Thank you.

 

Overestimated peak strength for cube compression. Abaqus/Explicit

Submitted by MrsTgr on

Hi,

I have done compression test for concrete cube using Concrete damaged plasticity model. I assigned BC in Reference point which I coupled with a surf of the cube.

I have got stress-strain curve that looks nice, but Peak strength is 2-3 times higher than it should be.

Ia have uploaded pic of force-displacement.

Can anybody help me?

Thanks

ABAQUS: Thermal stresses in a rectangular composite plate

Submitted by Anonymous (not verified) on

Trying to model a crossply square plate with a sinusoidal temperature loading (uniform along the thickness). I am trying to match the results by Kant et al 2008 and Rohwer et al 2001. I am modeling the compoosite as a 3-D solid elements (making a part and dividing into 4 layers). I always obtain transverse shear stress on the 90 degree layer at 0,b/2,z to be zero.  My results match with that of the paper when I have a single layer of orthotropic material but they dont match when I have 4 layers of equal thickness and an aspect ratio of 5 (length/thickness).

 

Short Course on Mechanics of Foams

Submitted by Patrick Onck on

A short course on the “Mechanics of Liquid and Solid Foams” will be offered at CISM, the International Centre for Mechanical Sciences in Udine, Italy, 13-17 July 2015 (see brochure attached).

The course will focus on relationships between the cellular microstructure and nonlinear mechanical behavior of liquid and solid foams, and foam-like biological and synthetic materials. Theoretical models, experimental methods, and numerical simulations will be presented. The course is aimed at PhD students, postdocs, and researchers in academia and industry.
